Satellite orbit :

The apogee(the point in orbit farthest from earth) and the perigee (the point in orbit closest to earth) of an elliptical orbit of an earth satellite are given by $\"\"$ and $\"\"$ , then the eccentricity of the orbit is $\"\"$ .

$\"\"$

The highest point above the earth is $\"\"$ .

The lowest point closest to the earth is $\"\"$ .

Find the eccentricity of the orbit.

The eccentricity of the orbit is $\"\"$ .

Substitute $\"\"$ and $\"\"$ .

$\"\"$

$\"\"$ .

Therefore, the eccentricity of the orbit is $\"\"$ .

$\"\"$

The eccetrincity of the orbit is $\"\"$ .
